Title: Method for judging rotary reference position of rotary body
Inventor: OGAWA SUMITAKA
IPC: G01M15/04
Filed: 1987-10-27
Abstract: PURPOSE:To judge the rotary reference position of a rotary body correctly, by provid ing parts to be detected, which are arrange in the rotating direction of the rotary body at a specified angular interval, providing detecting elements, which are arranged in the vicinities of said rotary locus, and detecting a set of signals, which are generated at the same time. CONSTITUTION:During the operation of two-cycle engine, pulses are detected through pickups 13a and 13b in correspondence with the rotation of a rotary body 10. When a power source is turned ON, initialization is performed in a control circuit 16 at the same time. Interruption INT1 and interruption INT2 are inhibited. Then a signal level at an input port P1 is received, and whether the signal is at '1' or not is judged. Implementation of '1' is waited. When P1 is '1', whether a P2 input signal is '1' or not is judged. Implementation of '1' in both inputs P1 and P2 is waited. In this constitution, even if the pulses for the rotary reference positions are inputted at deviat ed times due to the errors in manufacturing, the rotary reference positions of the rotary body are judged positively. After ignition commands are issued, implementation of '0' for both the P1 and P2 signals is waited. A counted value is made to be 1. The inhibition of all interruptions are released. A main routine is executed, and the ignition timing is determined.

Title: Oscillating actuator
Inventor: SUZUKI YUTAKA
IPC: B06B1/04
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To limit a moving amount of an oscillating actuator in a direction separating from the supporting base of the magnetic circuit of the oscillating actuator, and prevent generation of unrecoverable deformation or breakage, by forming a stopper facing the back face of the magnetic circuit and fixed at the outer periphery of the supporting base. SOLUTION: At an outer periphery or an outer edge of a supporting base 10, a stopper 7 with a structure facing the back face of a yoke 1 serving as a part of a magnetic circuit is formed in such a shape as to straddle the yoke 1 and a supporting rubber 12 with a clearance provided so as not to interfere with movement of the magnetic circuit due to normal operating vibration. The stopper 7 is extended from the outer periphery of the supporting base 10 in such a shape as to straggle the back face of the magnetic circuit with a clearance provided.  Therefore, even if external force in an axial direction is applied to the magnetic circuit due to, for example, the dropping shock of a mobile communication apparatus, its moving amount in a direction separating from the supporting base 10 of the magnetic circuit is limited by the stopper 7, thus enabling to prevent excessive force from being applied to a damper 8 and the supporting rubber 12, and reduce unrecoverable deformation or breakage.

Title: Method for measuring variation in water temperature of sea water due to discharge of warm effluent
Inventor: YOSHII SOSUKE
IPC: G01J5/48
Filed: 1986-11-18
Abstract: PURPOSE:To measure a three-dimensional water temperature distribution with high density, by coloring a warm effluent by the dyestuff of prescribed concentration and photographing it, deriving an integrated temperature distribution in the water depth direction by analyzing the image of its photograph, and assuming a temperature distribution in a warm effluent layer. CONSTITUTION:As the warm effluent 1, its temperature is higher than an ambient sea area 2, therefore, a warm effluent layer 3 is formed and flows down. A temperature distribution 4 in this layer 3 is the highest on the level of the water, becomes lower in the water depth direction, and a water level temperature TS can be detected by an infrared-ray image. Subsequenlty, when the warm effluent 1 is colored by dyestuff, and photographed from the upper part by a camera, the variable density of chromaticity which appears in the image shows that which has integrated with layer 3 in the water depth direction. By comparing and converting the variable density of this color with the chromaticity when colored water is photographed in a reference temperature position, for instance, an outlet 6, a value A integrating the temperature distribution in the water depth direction is derived. By the temperature TS by an infrared-ray image and the integral value A by analyzing the image of a colored effluent photograph, a water temperature distribution of the warm effluent layer 3 of an object sea area can be derived. Subsequently, from these various values, a water temperature at an arbitrary point of the warm effluent can be measured with high density.
